Replying to Compound stress?

Hey NSG i had a super stressful day today but i am not really sure why. I woke up and had a normal morning but then i started a little school work (i only had to write like a paragraph) but for some reason i just got into a state while writing that i was really fucking done with school and i had no patience at all. I had to do a bit of cleaning after to which if one thing went wrong i would like punch the vaccum and throw it away from me. It was like i was out of control i really hated it. the rest of the day was just a huge shitshow of uneplained stress. I was trying to find a reason. Could it have been like stress compunding up from like the last month of school which was really difficult but i wasnt really stressed though it. but today just that one paragraph just broke the dam? has this happened to anyone else?
